Abstract: The head wheel of a video recorder-reproducer is equipped with a set of four advanced read heads, in addition to the usual sets of four read and write heads, so that each advanced read head can read the contents of an oblique track on a magnetic tape on which one of the write heads will be able to record thereafter and which will be read still later by one of the normal read heads. The advanced read heads are so located that while one of them is reading a track, one of the normal read heads is out of contact with the tape. The advanced read heads are used for reading out audio sections of video tape tracks for processing and rerecording in accordance with a previously known processing procedure used in editing newly recorded video tapes for better audio recording. The normal read heads are available for an after-check of the rerecorded audio.

Abstract: An apparatus for damping movement courses of two bodies, in particular in a vehicle wheel/vehicle suspension system, having a piston sliding in a cylinder and dividing it into two work chambers, the two work chambers arranged to communicate with one another via respective oppositely acting check valves and via a variably asymmetrical damper valve adjustable in such a manner that upon a valve member movement the opening cross section for one flow direction decreases to the extent that it increases for the other flow direction, such that whenever in comparison with an active damper system energy would have to be supplied from outside, the damper force is substantially reduced to the value of zero.

Abstract: An end cap is releasably mounted on the end of a cylindrical hollow tube to form a reusable cylindrical yarn carrier or winding tube which carries a filamentary or fibrous yarn thereon. The cylindrical hollow tube is formed predominantly of a cylindrical laminated paper tube. A rigid polymeric or metallic insert is attached to the tube adjacent at least one end. While the tube is predominantly paper, the interface between the hollow tube and the end cap is formed of a material that is rigid, incompressible, and capable of being threaded. The abutting rigid walls of the hollow tube and end cap, when assembled, define a starting groove there between. When the yarn carrier has been emptied, the end cap is loosened or separated from the hollow tube and the residual fibers or filaments vacuumed or stripped away.

Abstract: A brake booster in a housing, having a servo piston slidably supported in the housing and having a piston rod protruding into the housing for transmitting a brake force. In the servo piston, a work chamber is provided for receiving brake fluid drawn after the opening of a valve from a reservoir or supply container and pumped via a pump or the like. The work chamber also communicates via a further valve or the like with a return line to the supply container. To improve valve closing and to shorten the idle travel, the valve preceding the work chamber and arranged for the admission of the brake fluid is embodied by a valve bushing in a blind bore of the servo piston and by a spring-loaded closing element, such as a ball. The valve bushing is disposed between the piston rod and the ball and is traversed by a pin or the like, capable of being acted upon by the piston rod, for lifting the ball from its valve seat.

The control bush is supported radially movably in the stepped bore.

Abstract: A positional fixation element is located on a first structural component and positionally fixes a second structural component, which is to be joined to the first component at a predetermined orientation relative thereto. The positional fixation element is substantially in the form of a stud, which protrudes beyond a reference plane of the first component. The positional fixation element is produced by means of a mandrel-like tool, which is pressed into the first component on an incline relative to the reference plane. In the process, material is displaced, so that on the one hand a groove-like indentation is formed, and on the other hand, an accumulation of material having a shape corresponding to that of the positional fixation element is created above the reference plane. The positional fixation element is suitable for positionally fixing electrical circuits, for example, or other components when glued or soldered onto the first component.

Abstract: Video signals from pre-recorded video tape or a video camera are received by the present invention and processed to provide the appearance of a motion picture film recorded image. The output of the invention may be provided directly for television broadcast or recording on video tape. Simulation of film frames is provided by summing a real time signal and delayed signals to create an interpolation of preceding and succeeding video fields. Addition of mixed, clipped and filtered noise to provide the appearance of grain in photographic film and alteration of the apparent contrast provide variable artistic attributes which are adjustable for the desired film appearance.
